1 Claim.

This invention relates to a collapsible chair.

The general object of the invention is to provide a collapsible chair including novel leg and back members.

Another object of the invention is to provide a collapsible chair including a novel back and head rest.

A further object of the invention is to provide a novel means for supporting the back and head rest of a collapsible chair.

Another object of the invention is to provide a novel arm rest for a collapsible chair.

Other objects and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawing, wherein:

Fig. 1 is an isometric view showing my improved collapsible chair;

Figs. 2, 3 and 4 are fragmentary sectional details taken on lines 22, 3-3 and 4-4, respectively, on Fig. 1;

Fig. 5 is a fragmentary elevation from line 55, Fig. 1, and

Fig. 6 is an end view showing the chair collapsed and bundled for transport.

Referring to the drawing by reference characters, I have shown my invention as embodied in a collapsible chair which is indicated generally at [0.

As shown the chair includes a pair of front legs I l and a pair of rear legs I2. The two front legs are connected by a removable round 12' while the rear legs are connected by a removable round l3. The rounds I2 and [3 have tapered ends as shown at M, Fig. 4, which fit in tapered sockets [5 in the legs. The front and back legs are connected by removable side bars I5 which are similar to the rounds I2. The front legs II are connected by a strap l6 which includes a buckle I'I which serves to prevent the front legs from becoming loose. The ends of the strap I6 are secured to the legs H by nails H which pass through the strap and into the legs.

The upper portion of each rear leg is provided with an aperture 18. The apertures I8 are in alignment and each receives a pivot pin H! which has a head at one end and is threaded at the other end to receive a wing nut 2|. A seat 2| has loops 2|" at each end which receive the rounds l2 and I3.

A back member is indicated generally at 22 and includes side strips 23 and a canvas connecting back 24 which is shown as having loops 25 at the ends receiving the strips 23. The strips 23 are provided with aligned apertures 25' which receive the pivot pins [9 as shown in Fig. 2 and thus the back is mounted for adjustment on the pivot pins. A washer I9 is arranged on each pin IS. The washers are arranged in holes I9" in the loops 25 and each engages the adjacent strip 23 to space the parts.

A head rest is indicated generally at 26 and includes side rails 21 and a canvas strip 28 having loops 29 engaging the side rails. The head rest rails adjacent their lower end have apertures 30 which receive the pivot pins H) to pivotally support the head rest in place.

Thus thepins l9 serve to support the back and the head rest and provide adjustment by releasing the wing nuts 2|, adjusting the parts as desired and then tightening the wing nuts.

To limit the rearward movement of the head rest rails each rear leg .is provided with a head rest stop 3| which is held in place as by screws 32. Thehead rest stop may be positioned so that it will limit the movement of the head rest to any angular position desired. In Fig. 1 the head rest is shown in an almost vertical position while the back is inclined. This positioning of head rest and back is so that the parts may be clearly shown.

Each stop member 3| engages and holds one end of a canvas arm 33 in place while the other end of each canvas arm is shown as provided with a slit 34 which may receive a pin 35 on the front leg to hold the forward end of the arm rest in place.

The chair in service position is indicated in Fig. 1 with the .parts secured together. After the chair is collapsed by loosening the wing nuts 2| and removing the back rest and the rounds it may be arranged in a bundle such as shown'in Fig. 6, with the various parts in parallel relation and may be held together as by a strap 36.

From the foregoing description it will be apparent that I have invented a novel collapsible chair which can be economically manufactured and which is sturdy and is quickly assembled and disassembled.

Having thus described my invention, I claim:

A chair including a pair of front legs and a pair of rear legs, side bars connecting the front and rear legs, a front round connecting the front legs, a rear round connecting the rear legs, a seat secured to the front and rear rounds, a back member, said back member comprising a pair of side strips and a back connecting said side strips, the upper portion of each rear leg having an aperture therethrough, said apertures being aligned, a removable pivot pin arranged in each aperture, said back member side strips being arranged between the rear legs and each having an aperture near the middle thereof receiving the adjacent pivot pin, a head rest, said head rest comprising side rails and a strip connecting the upper ends of said side rails, said head rest side rails being arranged outside of the rear legs and having apertures in their lower ends receiving said pivot pins, the inner ends of each pivot pin adjaceniiback memben side stnim, the: outenend of each pivot pin being threaded and having a wing nut thereon, each wing nut releasably engaging the adjacent head rest side rail, whereby the relative position of the back member and head rest may be adjusted, a headrest stopmember secured to each rear leg and extending outwardly from each rear leg, each stop member including a portion in the path of movement of the head rest side rail.
